The utility model which provides a movable model hand consists of a palm and arms and is characterized in that a concave part and an upper arm, the upper arm and a lower arm are respectively connected through a concave convex chimeric structure, and the concave part and a convex part can be turned, and a front arm and the palm, the palm and fingers and each of the finger joints are respectively connected through the concave convex chimeric structure. The utility model has the advantages that each joint of the model hand comprising the knuckles can be moved about freely and can be adjusted to needed positions according to the needs of users, and the utility model also has the advantages of versatile changes, beautiful exterior and also light weight, not easy distortion and saving of wood.

Description

Mobilizable model's hand

The utility model relates to a kind of model, particularly a kind of mobilizable model's hand.

The present model's hand that uses, its joint component scarcely can be movable, stiff during use because of arm, make model's appearance single, lack variation, and, go up (above the foam model) if be placed on low weight model because they are heavier, the model is out of shape, influences result of use.If the model's arm that uses timber to make usually can be big because of the timber distortion, be difficult to guarantee that each product of model's arm is all the same, adopt wooden materials simultaneously, also can waste the resource of a lot of preciousnesses.

The purpose of this utility model provides all mobilizable model's hand in a kind of each joint, and its in light weight, combined and instant is fit to be used in combination with various mannequins.This model's hand does not use timber processing, indeformable, easy processing.

The purpose of this utility model is achieved in that a kind of mobilizable model's hand, form by palm, arm, it is characterized in that adopting concavo-convex embedded structure to be connected between recess and last arm, last arm and the lower arms, can rotate between jog, forearm respectively closes internode and is connected by concavo-convex embedded structure with finger, finger with palm, palm; Mobilizable model's hand can also be that structure is closed in the spherical female tuck pointing, has groove on the protruding ball, in the protruding ball fixed bar is set; The hook part and the fixed bar that collude nail flexibly connect, and the other end and recess are fixed; Mobilizable model's hand closes structure for the spherical female tuck pointing between its recess and last arm, last arm and the lower arms, has groove on the protruding ball, in the protruding ball fixed bar is set; The recess front end is a concave ball shape identical with protruding ball shape, and a through hole and a stepped hole are arranged on the recess, and the hook part and the fixed bar that collude nail flexibly connect, and the other end is fixed with recess on stepped hole by colluding the threaded portion that nails on.Mobilizable model's hand, the two ends of its spring respectively with a bit the fixedlying connected of forearm and palm.Mobilizable model's hand, its palm and finger, finger and each interarticular concavo-convex embedded structure are that fixed block embeds and is fixed on the palm and points on the corresponding position, the head of movable block is spherical, head is opened a groove, retention tab on the fixed block embeds in the groove, and groove is connected with nail with retention tab.

The utility model has the advantages that: each joint of model's hand, comprise that articulations digitorum manus can adjust to the desired position according to user's needs, variation is many, and is handsome in appearance, and in light weight, not yielding, saved timber.

With reference to the accompanying drawings in conjunction with the embodiments, the utility model is described in further details below.

See also shown in Figure 1, mobilizable model's hand, form by palm, arm, its feature is that recess 6 adopts concavo-convex embedded structure to be connected with last arm 1, last arm 1 with the joint between the lower arms 2, can rotate between jog, forearm 3 respectively closes internode and is connected by concavo-convex embedded structure with finger 5, finger 5 with palm 4, palm 4; Mobilizable model's hand, the spherical female tuck pointing is closed structure and can is between recess 6 and last arm 1, last arm 1 and the lower arms 2, has groove 13 on the protruding ball 11,12, in the protruding ball 11,12 fixed bar 14 is set; The hook part 151 of colluding nail 15 flexibly connects with fixed bar 14, and the other end and recess 6 are fixing; The spherical female tuck pointing is closed structure and can also is between recess 6 and last arm 1, last arm 1 and the lower arms 2: have groove 13 on the protruding ball 11,12, in the protruding ball 11,12 fixed bar 14 (as shown in Figure 5) is set, recess 6 front ends are a concave ball shape 61 identical with protruding ball shape, one through hole 62 and a stepped hole 63 are arranged on the recess 6, the hook part 151 of colluding nail 15 flexibly connects with fixed bar 14, and the other end is fixing with recess 6 on stepped hole 63 by the threaded portion 152 of colluding on the nail 15.Hook part 151 can be rotated around fixed bar 14; Can make recess 6 chimeric fixing by threaded portion 152 and screw with the protruding ball 11 in the last arm 1; In addition, at soft cushion rubber 154 of screw 153 bottom pads, utilize its certain elasticity, make protruding ball 11 chimeric better with concave ball shape 61, utilize soft cushion rubber 154 to play the effect of fine setting simultaneously, can not cause getting loose of joint because of the pine slightly of screw 153, can be because of screw 153 yet slightly tightly make joint tension, akinesia.According to the size of model's external force that hand bears, can adjust the degree of tightness of screw 153, make model's hand can bear certain external force and do not change the residing position of hand, to guarantee the stable of model's shape.

As shown in Figure 1 the two ends of spring 31 respectively with forearm 3 and palm 4 on a bit fixedly connected.Present embodiment is to pass spring 31 1 ends with a pin 32 to be connected with wrist, the other end passes spring 31 and is connected with palm 4 with pin 32, forearm 3 owing to be subjected to the traction of spring 31, makes palm 4 can do arbitrarily angled rotation on forearm 3 and stop at unspecified angle with palm 4.

As shown in Figure 2, palm 4 and finger 5, finger connects by concavo-convex chimeric structure between 5 each joint, (this end can be cylindrical to fixed block 51 1 ends, it also can be other geometry, present embodiment is cylindrical), embed and be fixed on the position corresponding on the palm with finger, the head of movable block 52 is spherical, head is opened a groove 53, other end retention tab 511 on the fixed block 51 embeds in the groove 53, groove 53 and retention tab 511 usefulness nail 512 are tightened and are formed an articulations digitorum manus, this articulations digitorum manus can be made 130 degree and rotate, and all is connected with such method between each joint and the joint, and the rest may be inferred, palm 4 and each finger 5 are linked up, and all activity is freely in each joint.Thus, finger is changed by user's needs and countless actions.

In addition, the utility model can adopt the technology of injection moulding, make each product accomplish striking resemblances by mould, improved the stability of product greatly, it is hollow that the inside of model's hand is made, and makes it to save material, weight reduction, enhance productivity, simultaneously model's hand can not cause because of material processed is improper yet and distortion improved model's appreciative value greatly.
